old firmware usb compatability

ive got my modules built for a traktor box 

im just wondering if i run a 16f877 with old firmware are there any compatability problems with the usb module

thanx for such a wonderful project

No problems at all!

The USB module is “just” a MIDI-Interface (“converts” USB to MIDI).

It`s outputs and inputs are conform to the MIDI standards. So you can connect every MIDI device (or MIDIBox) you want ;D

 

            thanx very much for that
